A: The program does not run from the CF card. However, a very large program (too large to fit on the CPU: drive) can be compiled into CR1000 main memory from the card if the binary form of the compiled program does not exceed the available main memory (p. 330). 8.4 Telecommunications and Data Retrieval Telecommunications, in the context of CR1000 operation, is the movement of information between the CR1000 and another computing device, usually a PC. The information can be programs, data, files, or control commands. Telecommunications systems require three principal components: hardware, carrier signal, and protocol. For example, a common way to communicate with the CR1000 is with PC200W software by way of a PC COM port. In this example, 348
